Beta access

Become a tester.

Help us ship Seaman Log to seafarers everywhere. Free early access, every new feature first, direct line to the team.

Closed beta · iOS + Android
Why testers matter

Real rotations. Real feedback.

Seaman Log is built specifically for offshore seafarers — oil-rig crews, merchant marine, drilling crews, anyone whose work is measured in days at sea. We're in beta, and your real-world feedback is what makes the app reliable before public launch.

Testers get early access to every new feature, and the team reads every bug report personally. Beta access stays free for life as a thank-you.

iOS

Android

Join the Android beta.

Two-step opt-in via Google Play closed testing. Don't skip a step.

Google Play

  1. Make sure your Android phone's Play Store is signed in with the same Google account you use everywhere. Note this email. (Open the Play Store app → tap your profile picture top-right → confirm the active account.)
  2. Join our testers group by sending an empty email to seamanlog-testers+subscribe@googlegroups.com or by visiting https://groups.google.com/g/seamanlog-testers and clicking Join group. Membership is auto-approved — you don't need to wait for anyone to accept your request. The moment you join, you're in the eligibility list.
  3. On your Android phone (not desktop), open this link in a browser: https://play.google.com/apps/testing/com.seamanlog.app
  4. You should see a page that says "Become a tester" — tap that button. Wait for the green confirmation "You are a tester".
  5. Tap Download it on Google Play. Play Store will open with the Seaman Log listing. Tap Install.
Heads up: do NOT use any link starting with play.google.com/store/apps/... — those URLs only work for publicly released apps. While we're in closed testing, the only working install link is the one in step 3 above.

Allow up to a couple of hours for propagation

Google's tester-eligibility check isn't instant. After you complete step 4 ("You are a tester"), it can take anywhere from a few minutes to a couple of hours before Play Store actually shows the app to your account. If you see "Item not found" in Play Store, that's almost always propagation delay — wait 1–2 hours and try step 5 again.

Still seeing "Item not found"?
  • Wrong Google account. Open Play Store → profile picture top-right → confirm the active account matches the email you used to join the testers group. If different, tap the chevron next to the email and switch accounts.
  • Cached state. On Android, go to Settings → Apps → Google Play Store → Storage → tap Clear cache (do NOT tap "Clear data" — that signs you out of every Google service on the phone). Reopen Play Store and retry the testing URL.
  • Country mismatch. Open Play Store → profile → Settings → General → Account and device preferences → Country. Closed testing is rolled out to 177 countries — most are included, but if you see your country isn't in the list, email support@seamanlog.com and we can add it.
  • Brand-new Google account. If this is a Google account you just created and have never used Play Store with before, Play Store may need a few hours to fully bootstrap that account against the catalog. Browse a couple of free public apps in Play Store first to "warm up" the account, then try the testing URL again.
  • Still stuck after all of the above? Email support@seamanlog.com with the subject "Android beta install failing" and include: your Google account email, your phone model, and a screenshot of the Play Store error. We'll diagnose and add you manually if needed.
The brief

What to test.

Use the app the way a seafarer actually would. The scenarios below are the highest-value paths.

Found something else weird that's not on this list? Report it anyway. Off-list bugs are often the most valuable.
Reports

How to report bugs.

Open the app, go to Settings, and tap Report a bug. This opens your email app with our address pre-filled and your device info attached automatically — make sure that info stays in the email since it helps us reproduce the issue. Add a description of what you were doing, what you expected, and what actually happened. Screenshots help a lot.
